New technology developed at Dungeness specifically for maintaining continuously clean wash water. Superior performance for washes at landfills, construction sites, military bases, sand & gravel mines and more.
Removing solids and grit plays a crucial role in protecting pumps and other equipment in a treatment facility. WesTech is your single source for headworks equipment to maximize your screening, washing, dewatering, grit removal and grit washing.
The world’s surface is slightly over 70% water with billions of gallons of surface water and ground water used daily in society. Whether it is for drinking, hygiene, washing, cooking, recreation, agriculture, or power generation and industrial coolants, water is an undeniable source of life.
Our current solution is based on several years of experience with water treatment for car wash systems using Rotating Bed Biofilm Reactor technology (RBBR). When combined with a flotation unit, solids are separated from the water, most of which can be recycled back to the washing system. Rotating Bed Bio Reactor (RBBR) developed by Clewer and specific microbe population are patented and suitable for use larger scale applications.
Printing and Photo Processing Wastewater Treatment and Disposal. The printing industry and photographic processing produce a tremendous amount of waste water, from washing prints, cleaning between color changes, cleaning ink shipping containers and cleaning ink delivery systems. The wastewater produced is often contaminated with heavy metals and other highly toxic materials.
Turbidity is a measure of the loss of light transmittance through a liquid due to suspended particles. The more particles in the water, the murkier it looks or the higher the turbidity. This is a measure of the quality of the water. It is measured in units called Nephelometric Turbidity Units (NTU). Turbidity can be caused by run off after a heavy rain as erosion washes soil into a river or lake. It is often increased in the spring and fall when the water temperature at different levels in a lake change causing a...

Water wash air scrubbers are used for air pollution control in many industries that discharge gasses and smoke, to remove pollutants from the gas stream. A high-energy liquid spray washes the gas and removes pollutants from the air, These pollutants are then trapped in the water used for washing the gas. Safe disposal of air scrubber wastewater can be acheived by separating out the solids, using a Draygon Wastewater Evaporator.Draygon created the original "run-dry" evaporators, which can be run dry without...
Facility Operations And Maintenance Wastewater Reduction and Treatment. Steam Draygon evaporators can be used to reduce the volume of wastewater from many building and equipment maintenance operations, including: Air compressor condensate wastewater, air scrubber blow-down wastewater, boiler blow-down wastewater, cooling tower wastewater, floor scrub wastewater, machine cleaning wastewater, steam cleaning wastewater, pressure washing wastewater, storm runoff wastewater, heavy equipment cleaning wastewater.
Whether you find yourself in a hotel bath room, cruise ship cabin, hospital, office building, industrial plant, greenhouse, car wash facility or your own hot tub, the combination of certain temperature levels, stagnant water and the presence of biofilm in water systems is a potential recipe for disaster: an outbreak of Legionnaires’ disease. An outbreak of Legionnaires’ disease is often the result of negligence, having legal repercussions for responsible parties. Because of its chemical and biocidal...
Membrane technology has made major progress in recent years and is nowadays the method of choice for many processes in the chemical industry, wherever substances are to be separated efficiently and gently.
A prime example of this is dia-filtration, in which solutes and particles with higher molecular weights are retained while solutes with lower molecular weights are "washed" out of the process fluid.
Tracking the tiniest cracks – with H2O wastewater treatment. Heavy use, material fatigue and material faults can cause tiny cracks in plastic and metal parts. These are so small that they are invisible to the naked eye. But they can still be relevant to safety, e.g. on the wings of passenger jets. That’s why these parts are regularly checked for micro cracks. One way of doing this is the dye penetration process, where the part to be checked is first thoroughly cleaned. Applying a special dye and using...
As most of the largest industrial users of water, the paper and pulp industry have long treated water in accordance with environmental permits. Water is used in all major process stages, including raw materials preparation, pulp washing and screening and paper machines. Water is also used for process cooling, materials transport, equipment cleaning, general facilities operation and to generate steam for use in processes and on-site power generation. Lenntech provides sustainable complete solutions for ingredient,...
Hydrogen Peroxide as a Replacement for Sodium Hypochlorite
Hydrogen peroxide may be used in both mist scrubbers and packed tower scrubbers as a replacement for sodium hypochlorite (bleach). Like bleach, the process involves two concurrent mechanisms: 1) absorption of the odors (H2S) into the alkaline scrubbing solution; and 2) oxidation of the absorbed sulfide in solution.
H2S + NaOH → NaSH + H2O
4H2O2 + H2S → H2SO4 + 4H2O
Typical dose ratios are 5 parts H2O2 per part H2S or, when...
Direct reuse of wastewater in the product is not on the menu in the food and beverage industry, but the reuse of water for other purposes (e.g. washing) is now a priority. Most major F&B companies have made commitments to reduce their water consumption per unit of product, and reuse is an important part of the strategy for achieving this. Furthermore much of the growth of the industry is in emerging markets which typically have more limited, lower quality water resources than developed countries, creating...
Total Organic Carbon (TOC) is found in all water supplies as naturally occurring organic matter. Over many years of experience, medium or low pressure UV treatment has become recognised as an effective process step in the breakdown and reduction of TOC in water intended for use in pharmaceutical, health care, power generation and micro-electronics applications. In the latter case, ultra-pure water is used to wash silicon wafers on which even small deposits of carbon compounds on the wafers can severely affect...
CleanOxide Chlorine Dioxide can safely be used for washing fruit and vegetables, seafood, meat, mushrooms and many other foodstuffs. CleanOxide Chlorine Dioxide destroys bacteria including potentially harmful pathogens such as E.coli, as well as controlling fungi and fungal spores ensuring reduced risk for the consumer and increased shelf life for the produce. Residual chlorine dioxide left on the produce degrades rapidly leaving no harmful residues.
Scalewatcher North America, manufacturer of the original, patented and award-winning computerized electronic water-conditioner, states in its literature that the device is produced to last at least 20 years and comes with a 10 year warranty. However, no reports have been received on the longevity of the units sold since the company was launched over 20 years ago. Now a customer in Gilroy, California has come forward requesting a new Scalewatcher unit after the device she purchased in 1992 finally stopped...
Specializing in the manufacturing of the next generation of solid/liquid separation systems, Heron Innovators developed this Suspended Air Flotation (SAF) system for a customer in the truck washing industry. The skid mounted treatment system addressed the customer’s need for treatment of water reuse by removing suspended solids, oils, and grease. The solution Heron Innovators provided to the customer reduced surcharges prior to discharge to the municipal wastewater collection system.
