Digester Mixing

Monsal have expertise in providing digester mixing technology for digesters up to 8000 m3 volume mixing with conventional sludges, thick sludges, Enzymic Hydrolysis, thermal hydrolysis sludges and organic wastes.

Monsal SGM Digester Mixing systems use our proprietary Sequential Gas Mixing technology. The technology has been continually refined over a number of years to deliver very high levels of mixing performance for digesters. We have particular expertise in mixing thick sludges or sludges from advanced digestion processes.

We can demonstrate, through full scale testing, that our mixing technology delivers very high active volumes with the lowest Net energy on the market over other systems, including pump mixing, venturi mixing and unconfined gas mixing.

Our technology is proven on large scale digesters with low levels of maintenance and with no moving parts or components which can block/rag in the digesters are ideal for all digesters including wastewater sludges, biowaste, agricultural, MSW digesters.

Sludge Tank Mixing

Monsal AM mixing systems are designed for the mixing of sludges from wastewater or biowaste plants, and can be provided with guarantees on blend times and active volume to ensure optimal use of tank capacity.

The Air Mixing system is based on the principle of air injection into the liquid either on a continuous or sequential basis. Air is externally compressed and delivered through a series of mixing points within the tank. The high intensity airflow through each mixing point generates a stable mixing pattern in the tank which rotates the tanks contents.

Monsal supplies and installs custom designed mixing systems for all types of sludge holding tank applications. This includes raw, digested, secondary sludge holding tanks, and standard systems for tanks from 50 - 5,500 m3 are available. Monsal have particular expertise in the mixing of thick sludges. Systems can be applied to rectangular and circular tanks.

Monsal has developed designs which can guarantee effective mixing of all sludge types up to 10% DS concentration, enabling upgrading of existing process plant capacity. Monsal packages incorporate skid-mounted compressor sets, pipework, mixing manifolds, and Monsal proprietary control panels with PLC control for sequential and continuous operation. The Monsal Air Mixing system can be supplied as complete packages, including installation, commissioning and control panels to suit the customers' needs.

Product range

Monsal's Air Mixing Systems are designed to suit the specific conditions on site by our in-house team of design engineers, and are available for tank volumes 50 - 5500 m3 as standard.

Mixing systems are manufactured from predominately stainless steel pipe work and the system conforms with WIMES 4.01. Products are manufactured to ISO 9001:2008 and come with a full warranty. There are no moving parts or mechanical or electrical components within the tank ensuring a robust and low maintenance installation.
