Plating Wastewater Treatment Application: Wastewater generated from chrome and nickel plating operations. Prior Treatment Method: Chrome and nickel streams were segregated because of characteristics. Chrome was reduced from hexavalent to trivalent state then combined with the nickel stream. The full stream was then precipitated via typical hydroxide precipitation methodology. Broad swings in the contaminate concentrations resulted in poor treatment and the facility was issued several NOVs.
Let`s face it, wastewater is a tough, nearly thankless business. A lot can go wrong and before you know it, you`re in violation. Regulations ever increase, compliance becomes more difficult, and odors get the phone ringing. Equipment breaks down. Energy costs go higher & higher.
For this propose, AZUD has developed innovative wastewater treatment plants AZUD WW MBBR (Moving Bed Bio Reactor). This techonology is based on the growth of biomass in a plastic supports (carriers) suspended in the bioreactor mixed liquor. This carriers allow more concentreation of microorganisms per unit volume than a conventional system, reaching high quality effluent in a minimum area of implementation. In addition, our exclusive AZUD RC system allows remote management of automation and electromechanical...
The removal of contaminants from untreated water has become a leading issue, due to environmental concerns and the threat of future water shortage. An effective purification process is necessary to eliminate organic, chemical or other debris to meet stringent regulations for drinking water, as well as for the chemical, industrial, pharmaceutical and science markets.
Sometimes an `off the shelf` water quality monitoring product is just not available and it is necessary to engineer a complete bespoke monitoring solution. System integration demands a diverse range of abilities. PPM is experienced in designing the correct suite of instrumentation combining manufactured, distributed and factored products.
Wastewater treatment plants (WWTP) are subject to large variation in flow and load, not to speak of uncertainties on the composition of the incoming wastewater. On top of that, the activated sludge treatment process, as used by the vast majority of treatment plants, is difficult to control due to the complex behaviour of the biological process. Nevertheless WWTPs are run 24/7, with operators and management challenged to meet ever tightening environmental regulations.
In order to meet the operational demands of...
Disinfection of drinking water means the effective deactivation or killing of microorganisms that may be present in water. Disinfection of drinking water is essential to ensure our water is safe to and free from harmful bacteria even after it has been stored or transferred through a network of pipes before reaching the consumer. The use of chlorine based compounds is the most widely used technology around the world as it effectively kills the majority of harmful microorganisms and leaves a long-lasting residual...
UV technology has made tremendous gains in the last 25 years and is now recognised as a primary method of disinfecting waste water. atg UV Technology have researched the wastewater industry and identified the need for a range of compact closed chamber UV systems, which are easy to install into a pipeline, can deal with a wide range of water qualities and offer a high output within a small foot print. The advanced range of atg UV systems have successfully treated a wide range of fluids, in many different industries...
A wide range of sample acquisition and filtration systems are available to prepare even the most difficult of samples for reliable on-line analyser measurement. The correct choice is often critical to prevent analyser blockage and optimise performance. Cross Flow Filtration The PPM cross flow filter, is a simple in-line device used to protect an analyser from ingress of solids, for applications where sample quality is generally good but occasionally suspended solids may be present. The stainless steel filter...
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.
DEVISE ENGINEERING designs and constructs autonomous packaged systems for Tertiary Treatment aimed for water recovery and re-use.

DEVISE uses top quality Ultra-Filtration membrane modules and in the package is included all necessary equipment, systems and controls for a complete installation.
A wide range of capacities can be...
Using Oxygen to Solve Waste Water Problems
Lack of oxygen can cause inadequate purification or even anaerobic decomposition, as well as offensive odors. Injecting oxygen into sludge beds &/or piping allows you to:
* Reduce nitrogen levels
* Meet peak O2 demands
* Have a back up to your aeration system
* Pre-purify waste water
* Control odors
* Deter corrosion damage
* Meet increased requirements regarding waste water purification
In 2004-2005 LIFETECH`s laboratory worked out an advanced oxidation process (AOP) for removal of dioxins and furans (PCDD/F), chlorophenols and other contaminants from the BCD process wastewater. Consequently, our technology was installed and from April 2006 successfully used in the `Spolana-Dioxins` Project at SPOLANA a.s. in Neratovice, Czech Republic, as a part of Special Wastewater Treatment Plant. Our supply consisted of an ozone generator with the output of 5 kg O3/h at 10% w/w ozone concentration, two...
