Marsh Hydroil™ Silt traps

Marsh Hydroil™ Silt traps

WWith capacities ranging from 830-3400 litres, Marsh silt traps provide effective storage of silt and debris from vehicle wash-down facilities. Positioned ahead of an oil separator, the silt trap gathers and stores silt and sediment, and prevents it from entering the oil[...]

Oil separator alarm systems

Oil separator alarm systems

An oil separator alarm monitors the level of liquid in oil separator units. An alarm signal is generated when there is an excessive level of oil, liquid or silt, or when the unit requires emptying. An oil separator alarm is required on[...]

Gaia Sege© process design software

Developed by Marsh Industries, the unique Gaia Sege process design software uses core information to accurately calculate and tailor key variables ensuring total optimisation for individual applications. These precise calculations provide assurance to consultants, engineers, specifiers and contractors that the system is specifically designed to meet the appropriate standards of regulatory bodies. Sewage treatment plants For sewage treatment plants, the software uses established core process equations to accurately calculate and tailor key variables ensuring total processing optimisation for Biological Oxygen Demand (BOD), Total Suspended Solids (TSS) and Ammonia (NH4) reduction and removal. Gaia Sege software also uses ‘British Water Flows & Loads’ data to calculate initial flows and loadings whilst also calculating peak flows and levels. The programme can also calculate accurate sludge generation and storage on a daily basis, dependent upon final effluent standards required, ensuring the optimisation of primary chambers, individual clarifiers, diffused oxygen feed and final settlement chamber. Pump chambers Gaia Sege utilises current building regulations to calculate precise storage chamber sizes. Pump systems are determined by using friction head loss calculations based on minimum self-cleansing velocities in order to specify the best possible pump(s) for the application. Grease traps Appropriate grease trap sizes are generated by accounting for the amount of grease and flow generated from the grease producing facility whilst providing adequate retention time befitting of these variables. Storm Dammer water attenuation tanks Marsh Industries’ rainfall storage sizing programme, Gaia Storm Dammer, can simulate the calculated flood storage required for any prolonged period within a set geographic area (ie, 1 in 5 years or 1 in 100-year rainfall).
