Enva supplies a comprehensive range of wastewater treatment chemicals, biological products and technical support services for industrial and municipal treatment applications. Combining practical site knowledge with strong chemical treatment expertise, our specialist team works with customers to improve treatment performance, resolve operational challenges and optimise compliance across a wide range of treatment processes.
Maintaining wastewater treatment performance can be challenging when faced with changing effluent characteristics, tightening discharge limits and increasing operational pressures. Enva provides chemical and biological by expert technical advice to help industrial and municipal operators protect discharge compliance, optimise treatment solutions supported treatment efficiency and reduce operational issues.
Whether you need support with sludge dewatering, phosphorus removal, heavy metal treatment, biological process recovery or odour control, our specialists can assess your requirements and recommend the most effective solution for your site.
Effective liquid-solid separation is critical to wastewater treatment performance. Enva supports customers with the selection and optimisation of flocculants and coagulants for filtration, sludge dewatering, clarification, settlement and effluent treatment processes.
Foam in industrial processes and effluent treatment systems can reduce equipment capacity, increase processing time, affect product quality and create operational difficulties. Effective foam control helps maintain treatment capacity, improve process stability and reduce unnecessary cost.
Phosphorus is present in many industrial, food, pharmaceutical, chemical and municipal effluent streams. Alongside nitrogen, phosphorus is classed as a nutrient and can contribute to eutrophication and algal bloom when discharged to rivers, lakes or receiving waters above permitted limits.
Enva also supplies a wide range of general treatment chemicals used in water and wastewater treatment, including pH correction, coagulation, oxidation, disinfection, nutrient dosing and process support applications.
Biological effluent treatment depends on a healthy and active biomass. Activated sludge plants can become deficient in essential macro and micronutrients, reducing the ability of bacteria to convert soluble organic material into biomass, carbon dioxide and water.
Sludge bulking in activated sludge plants can cause poor settlement, biomass loss and reduced biological treatment performance.
Heavy metals can be present in wastewater from a wide range of industrial processes and are often controlled by strict discharge licence limits. Enva’s heavy metal removal products help treat contaminants such as lead, nickel, copper, mercury, chromium, cadmium, selenium and zinc.
PHOSPHIX® continuous ion exchange process for the removal and recovery of phosphate from industrial and municipal wastewater.
Changes in wastewater loading, temperature, pH or chemical composition can disrupt the microbiological population in an activated sludge system. This can lead to poor settlement, reduced BOD removal, foam, scum build-up, filamentous bacteria, nitrification challenges and increased compliance risk.
Ammoxider is Enva's specialist microorganism-based solution for ammonia reduction in wastewater treatment systems. It supports ammonia reduction through a natural biological process that is not conventional nitrification, with treatment changes possible in as little as 48 to 96 hours depending on system conditions.

Fats, Oils and Grease (FOG) entering the wastewater system causes several problems, both in the drains and wastewater collection system, and in wastewater treatment plants themselves.
Odour issues in wastewater and sludge treatment can arise from sulphides, ammonia, sludge tanks, scrubbers, off-gas systems and other process sources. Enva supplies odour control chemicals for both prevention and masking of offensive odours.
Enva also provides odour abatement solutions including air scrubbing systems, air filters, photoionisation systems and activated carbons.
Enva supplies activated carbon media for water treatment, wastewater treatment, air purification and odour control applications. With access to more than 150 activated carbon grades, we help customers select the most appropriate solution based on contaminant type, operating conditions and treatment objectives.
Choosing the right treatment product is only part of the solution. Enva's wastewater specialists work closely with customers to understand treatment challenges, identify root causes and optimise process performance.
By combining practical operational experience with specialist chemical and biological expertise, we help customers achieve sustainable improvements in treatment performance and compliance.
For support with wastewater treatment chemicals, biological products, plant troubleshooting or product selection, contact Enva to discuss your site requirements. Our team can help assess wastewater treatment challenges, recommend suitable products and develop a practical treatment approach for your process, compliance and operational needs.
