Selecting the correct chemical product to optimise waste water treatment processes requires an in-depth knowledge of the chemistry involved. Our team combines this expertise, years of experience and cutting edge technology to produce the right solution for every situation.
Selecting the correct product for liquid-solid separation requires expertise in applications such as filtration, sludge dewatering and settlement as well as the chemistry involved.
Our range of wastewater treatment chemicals include high activity inorganic coagulants, and low and high molecular weight polyelectrolytes. Our flocculants are available in cationic and anionic charges, emulsion or powder form. These products coagulate colloidal material and suspended solids into larger ‘flocs’, which then settle, filter or dewater more effectively increasing throughput, yield and separation efficiency.
The generation of foam can cause serious problems within treatment processes. Its existence presents difficulties in the operation of industrial plant and can affect the quality of the finished product. If not properly controlled, foam can reduce equipment capacity and increase processing time and production cost.
Our solutions are designed both to counteract existing foam (defoamers), and also to prevent foam formation (antifoams). We provide concentrates and emulsions, in both technical and food grades, and we can also develop products for specific customer requirements.
Phosphorus is found in many different processes and effluent streams. Along with Nitrogen, it is grouped as a ‘nutrient’ which, when released into rivers and lakes, causes eutrophication or algal bloom.
By applying wastewater treatment plant chemicals, phosphorus can be precipitated from process and effluent streams, and converted into a more manageable form. Phosphorus removal requires knowledge of both the source of the problem and the science required to effectively treat it. Products are supplied in both inorganic and organic forms as liquid precipitants and coagulants, designed to specifically target the phosphate (PO4) ion and convert it to an insoluble form.
Heavy metals are used across a range of industrial processes and are often present as contaminants in waste water. As they can often be toxic in nature and are strictly controlled by discharge licence limits, these metals must be removed as part of an effluent treatment programme. Metals that can be successfully removed from an aqueous matrix include lead, nickel, copper, mercury, chromium, cadmium, selenium and zinc.
Our products are designed using a range of chemistries to react with heavy metals in solution, and form insoluble precipitates. These can then be removed in solid form and disposed of safely. Through a series of laboratory tests, we identify the level and nature of heavy metal contamination and select the best treatment regime. This can include pH optimisation, co-precipitation techniques and the appropriate product application.
Biological activated sludge is dependent on a healthy biomass that require both macronutrients and micronutrients to perform effectively. These elements are required at low or trace concentrations to promote the growth and activity of all bacteria, which perform the conversion of soluble organic material to biomass, carbon and water. Our range of nutrient products contains select ratios of Nitrogen, Phosphorus and trace elements. These elements are in a bio-available form and can be dosed to activated sludge tanks and are easily assimilated by the biomass.
Our specialist range of wastewater treatment chemicals includes inorganic suspensions designed to provide a nucleus around which floc forming bacteria can attach. In activated sludge systems where settlement is a problem, this can be the ideal solution. Our products provide alkalinity to the system, which can act as a buffer to pH shocks and also assists in biological nitrification and can also be utilised as a conditioning agent for sludge dewatering.
We supply a range of chemicals for the abatement of offensive odours e.g. hydrogen sulphides, mercaptan and ammonia. Our expert team assess the odour source to identify the most appropriate solution and subsequent effective application.
Many sludges, especially sludges which are low in inorganic content can be difficult to dewater using polyelectrolytes alone. The application of our chemical products allows us to manipulate the sludge charge more effectively, which in turn leads to more effective flocculation and dewatering. The application of our products has increased dewatered sludge dry solids content by up to 5% resulting in significant savings in transport and disposal costs.
We also provide a range of food grade products, which are used to increase the efficiency of separation processes. Applications include fermentation, dairy processes and any food related separation technology.
