Biological wastewater treatment

The AnoxKaldnes™ Hybas™ hybrid process combines AnoxKaldnes™ MBBR biofilm technology and an activated sludge process in the same tank. The Hybas™ hybrid process is suitable for nitrogen removal from municipal wastewater and for some industrial applications. High nitrification is achieved with a reduced suspended sludge age

In moving bed biofilm reactors the buoyant media is free to move within an aerated reaction chamber. The MBBR integrated fixed film activated sludge (IFAS) is essentially an activated sludge suspended growth process but with the biomass fixed to the media. It can perform all the same process variations such as nitrification, denitrification and

Unexpected breakdowns, planned upgrades or seasonal load increases can severely impact wastewater treatment processes, leading to non-compliance, reputational damage and operational losses.

The Siltbuster range of Moving Bed Biofilm Reactors (MBBR) is designed to provide packaged plug and play aerobic biological treatment, easy to operate and easy to maintain. Based on established fixed film biological treatment, the MBBR uses media with a specific area of up to 800m2/m3, providing a substantial greater treatment capacity – up to

A flexible and versatile aeration system for the treatment of wastewater and when both mixing and air are required. It can be fed by atmospheric air, oxygen enriched air, pure oxygen or other gaseous or liquid substances to suit your application: elevated oxygen transfer figures; installed in a wide range of applications without the need to empty

The Triton® TR Series aerator is designed to provide reliable performance levels in challenging, heavy debris conditions. Featuring a stainless steel, dual-bladed propeller, the Triton® maximises oxygen transfer and mixing capabilities for water, wastewater and effluent treatment systems. Mixing-only option for biological nutrient removal (BNR

Biostyr™ biofilters combine a biological reactor and a physical filter in a single structure for the removal of organic, nitrogenous and particulate pollution in the treatment of municipal and industrial wastewater. Biostyr™ biofilters are available in several configurations for carbon removal, nitrification, nitrification / denitrification, and post-denitrification, and have a modular structure

The Volcano III floating lake aerator provides extremely high flow rates resulting in huge volumes of water turnover and high DO or dissolved oxygen levels. Volcano III is suitable where a minimal surface display is required but efficient aeration is of importance. It has high LPM pumping rates and oxygen transfer capabilities. Options to add

Aquatreat's anti-fouling aspirators have been developed in response to the growing challenges posed by flushed wipes and rugs, and other heavy debris conditions in water and wastewater treatment systems. Operating without aerosols or any need for fine screening, the anti-fouling aspirators can be integrated into either new or existing treatment

Colloide solutions for effluent treatment are determined by site-specific factors including: existing plant size / capacity / condition; raw water quality; required final quality of treated effluent; space available; etc. Activated sludge treatment uses microorganisms cultivated in the treatment process to break down organic matter into carbon

The digestate treatment system, designed by Colloide, is built around the ultra-efficient Selective Vaporisation system. Colloide's system is compact with a small footprint, and highly innovative with low energy and low chemical consumption. Separated liquor or unseparated liquor and solids can be treated to selectively remove ammonia and only a

Colloide can provide packaged MBBR system solutions including tanks, media, and screens. Specialising in engineering a lot of treatment capacity into a small volume Colloide systems can perform better than conventional activated sludge systems. The Colloide systems are highly flexible and can be used in a variety of configurations to achieve the

Integrated fixed film activated sludge (IFAS) process combines biofilm technology and the conventional activated sludge (AS) treatment. IFAS technology is compact, cost effective and retains high biomass concentration in the reactor. This process uses suspended a suspended buoyant media, usually made of polypropylene (PP) or high density

Puriflo has wide experience in building sequential batch reactors, a form of activated sludge treatment in which both aeration and settling take place in the same tank. The process can only be applied in cases where the flow to the plant is suitable or where it is possible to discharge a large volume in a short time. It is possible, by the

The SolarAir solar-powered diffused lake aerator provides the end-user with a totally off-grid solar aeration solution, and can be used at remote locations where a power supply is not easily accessible. SolarAir is available with many additional options including online monitoring and management. Installation and maintenance services are available

A wide range of municipal or industrial effluents are treated by fixed film or suspended media biological processes. Aquatreat engineers can assist with existing process plant or advise on the most effective options for new facilities or extensions. Services include: sampling; testing; pilot testing of plant; provision of temporary or permanent plant
