ANITA™ Mox is a moving bed biofilm reactor (MBBR) for treating high-ammonia effluents. The system removes ammonia from effluent before it is recycled back into the digester for further treatment or discharged in the environment. Compact and flexible process, easily adaptable for upgrading of existing plants; alternative to building new biological

High- and low-speed surface aerators allow versatility across a range of industries and wastewater treatment applications. They provide efficient wastewater aeration and intensive mixing capabilities which are environmentally- and fish-friendly. Units can be supplied as fix mount or with floats. The turbulent directional mixing and jet propulsion

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 Select Series 2 Torrent floating lake fountain produces a bubbling froth of extremely aerated water. It is available in a range of sizes from 0.75 to 5.5kW: increased suction screens are available on vertical units to increase the suction area which results in less maintenance; optional cable length and in-house cable sizing; lightweight

Phragmifiltre® is a reedbed technology that provides complete treatment of macerated or raw sewage in a single wetland system, with no pre-settlement and little or no power requirement. The system can treat raw non-settled sewage from 20 to 5,000 PE achieving removal efficiencies of 92% COD, 97% BOD5, and 97% suspended solids

Membrane Bio Reactors (MBR) from MSE Systems combine activated sludge treatment with a membrane liquid-solid separation process. The system uses low pressure Micro Filtration (MF) or Ultra-Filtration (UF) membranes, eliminating the need for clarification and tertiary filtration. MBRs are suitable for municipal and industrial wastewater treatment

Puriflo's membrane bioreactors feature submerged aerated media, offering high performance with low electrical running costs and minimal maintenance. They are manufactured with flat-sheet membranes and are designed specifically for each application. Services include installation and commissioning

Biopipe+ and Bioflo+ biological filter media are designed for use in Recirculation Aquaculture Systems (RAS). Warden Biomedia's uniquely-designed media provides a large protected surface area for biofilm development and optimal conditions for bacteria culture growth. RAS are designed to recirculate the water from fish farming tanks after it has

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

Puriflo specialises in the design of submerged aerated media plant for treating waste water in food processing industries. Submerged aerated media plant can deal with much higher loadings per cubic metre of tank volume than an activated sludge plant. No daily checks are required on the mixed liquor solids volume. Submerged aerated media plant uses
