Why do I need a water treatment specialist? Wont some equipment from the store work just fine?
When it comes to water treatment there is no turnkey solution that works for all water sources. The water that is supplied changes throughout the planet while also changing with the seasons. So there may be a setup in New York that works really well on their water source but it might not work well in California. Each water treatment system needs to be adjusted for based on the water that will be processed within the system. So if we want to find the perfect equipment to process our water we need to find a way to figure out what’s in the water. This is where a water sample should be obtained and sent in for analysis.
City Water vs Well Water?
A water analysis is important so a water treatment professional can assist you in what you need to do to treat your water. When it comes to your water sources, the two most common are well water and city water. When people are not in largely populated areas with no good way of getting city water, they usually have to use well water from their land. Well water is more cost effective as it is being obtained from land the customer owns. However, since water is a universal solvent it will obtain particles and compounds it comes into contact with. So as you can imagine, when you have a large well underground it will dissolve minerals, salts, and many other materials in the ground. Depending on where you live the composition of what’s in your well water depends on the ground beneath your feet. It also depends on what else can get into the water from nearby areas. We have all heard stories of ground water and well water being tarnished by chemicals from nearby businesses. So it is good to ensure your water is safe for consumption. This can be done by obtaining a water sample and sending it to your water treatment professional. He can tell you what you need to get the best water for your home or business.

One of the biggest problems of many existing systems is not that a wide range of data is not stored. The problem is that the people who need to view and use the data cannot retrieve it because it is not held in a system designed for wide or timely access. Typically, data is held in a variety of systems and the growing need over time for wider access to that data soon exceeds the design specification of the system.
There are a number of specific limitation...
Abstract
This is a summary report of a detailed investigation in which the analysis of synthetic organic chemicals by Gas Chromatography (GC) and Liquid Chromatography (LC) was conducted on raw and finished water samples collected from public water supplies using ground water as a source of drinking water. All water systems sampled are known to be contaminated by volatile organic chemicals except for one (the “control” system). This work investigated the potential presence of non-volatile and semi-volatile...
Up to now, the recovery of precious metals used as catalysts in chemical processes has involved the use of incineration. Now, however, a British-Swedish joint venture has developed a process which uses supercritical water oxidation instead, which provides many economic and environmental advantages.
Precious metals are used extensively in catalysts in a wide range of industrial chemical processes. Sometimes they are used in a homogeneous form, but more often fixed to a solid support for ease of handling. In many...
The harm caused by toxic industrial effluents to sewage treatment works, has been recognised for many years. These can cause reduction in biodegradable efficiency, with an associated requirement for longer treatment time, and in extreme cases, toxic shock can kill off the secondary tanks.
Currently, the presence of harmful industrial effluents is made evident by their effects on the overall treatment cycle at the works. An increasing frequency of incidents has led to a call to establish or improve methods of...

A wave of privatization is rolling through the water industry – at the environment‘s expense? In order to provide an answer to this question, the Environmental-Rating agency oekom research AG, Munich, put a number of water supply companies and manufacturers of water appliances to the environmental test. In results published today, oekom identifies the British water supplier Severn Trent as the environmental leader of the water supply group with a B grade in the overall Environmental-Rating. The Austrian water...
1.1 Scope and Objectives
A small number of viable options are presently available for the bleaching of wood pulp (delignification and brightening) during the manufacture of pulp and paper. The use of chlorine dioxide (ClO2) in the bleaching process has largely superceded the earlier use of Cl2, or elemental chlorine, in the majority of North American pulp mills: It was discovered over a decade ago that the previous widespread use of Cl2 contributed to the production and subsequent release to the environment of...
Within the last decade, implementation of state and federal regulations and other local codes have changed biosolids processing in Florida. Previously, biosolids stabilization varied greatly among the state’s 3,500 to 4,000 wastewater treatment facilities. Public and privately owned wastewater treatment facilities were required to stabilize their biosolids to a minimum Class C standard for land application, with most facilities using aerobic or anaerobic digestion. Requirements for septage solids stabilization,...
Abstract
This report presents the results of a study to examine and evaluate the economic, environmental and social benefits of plant protection products (PPPs) in agriculture with the main emphasis on the economic aspects. The approach followed was to carry out four case studies - each covering a single crop in a specific region of major production-comparing standard, integrated and organic production systems. The four crop/region case studies selected were: apples (Trentino-Adige, Italy), ware potatoes (Flevolan...
Introduction Sustainability or `sustainable development` has become a term which is frequently applied to land use and social planning and resource issues. Sustainability is a concept which draws attention to development practices which can degrade natural ecosystems and deplete natural resources. If development is defined broadly to include any cultural activity, then sustainable development may be defined as any practice that meets the needs of the present population without compromising the ability of future...
There has been a sharply falling trend in the total volume of sales of agricultural pesticides in the EU between 1991 and 1995. But this was reversed in 1996. From 1991-1995, EU sales of pesticides, measured by weight of active ingredients (ai), fell by 13%. They then rose by 6% between 1995 and 1996 to stand at 299,826 tonnes ai. But this still put them nearly 8% below the 1991 figure. The use of lower-dose pesticides has been a key contributor to the fall in weight of active ingredients sold in recent years....

At the beginning of the 1970s, agriculture in the region became increasingly intensive. The quality of beer was being sacrificed for quick and high returns on sales. Neumarkter Lammsbräu wanted to safeguard the quality of its products and develop a strategy for success. The company...
` In order to determine the impacts of a particular discharge on ambient water quality, it is usually necessary to model the diffusion and dispersion of the discharge in the relevant water body. The approach applies both to new discharges and to upgrading of existing sources. This note provides guidance on models that may be applicable in the context of typical Bank projects.`
Introduction
Mathematical models can be used to predict changes in ambient water quality due to changes in discharges of wastewater. In...
Explosives-contaminated process waste waters can be subdivided into two categories: red water, which comes strictly from the manufacture of TNT, and pink water, which includes any washwater associated with load, assemble, and pack (LAP) operations or with the demilitarization of munitions involving contact with finished explosive. Despite their names, red and pink water cannot be identified by color. Both are clear when they emerge from their respective processes and subsequently turn pink, light red, dark red,...
Containment treatments are often performed to prevent, or significantly reduce, the migration of contaminants in soils or ground water. Containment is necessary whenever contaminated materials are to be buried or left in place at a site. In general, containment is performed when extensive subsurface contamination at a site precludes excavation and removal of wastes because of potential hazards, unrealistic cost, or lack of adequate treatment technologies.
Containment treatments offer quick installation times and...
The U. S. Department of Energy (DOE or the Department) is taking a structured approach for the determination of its low-level waste (LLW) disposal needs through the development of this Low-Level Waste Projection Program Guide (referred to as the Guide). The Department has developed this Guide as part of a process to improve the management of DOE LLW. This Guide has been prepared by the Office of Environmental Management (EM) and establishes a consistent methodology for forecasting the volume and characteristics...

The Regional Superfund Ground Water Forum is a group of ground-water scientists, representing EPA`s Regional Superfund Offices, organized to exchange information related to ground-water remediation at Superfund sites. One of the major concerns of the Forum is the sampling of ground water to support site assessment and remedial performance monitoring objectives. This paper is intended to provide background information on the development of low-flow sampling procedures and its application under a variety of hydrogeol...
Full Abstract:
Carbon filters for domestic water treatment are increasingly popular, but many water treatment professionals may not realize the impact carbon`s `mesh size` can have on a filter`s performance. Mesh size, which indicates the range of particles sizes in a particular carbon product, is an important physical consideration. Other physical properties of activated carbon include its apparent density, which refers to its weight-to-volume ratio; and its abrasion resistance, which refers to its ability to...
