Introduction In recent years, there has been a growing global desire to restore the environment and protect it from the harmful effects of all forms of pollution. Particularly in the wastewater treatment market, an increasing industrialisation is leading to stricter standards for the disposal of wastewater and to a change in technology standards. Today, both municipalities and the industry must treat their wastewater in such a way that they comply with limit values set by the national environmental protection authorities when discharging it...

The greasy wastewater is fed via the main supply line to the main tank of the system. Due to the difference in density and gravity, heavy particles sink to the bottom of the tank and settle there as sludge. Light materials such as oils rise to the water surface and form a layer of grease. Separation phase ^ ^ ^ Sludge 2. If the water level in the main tank rises due to a constant water inflow, the flotation process starts when the...

Subsequently, any dirty water still in the high separation container is drained off into the main tank so that it can be treated during the next cycle. At the same time, various cleaning valves are opened to clean the various system components and prevent dirt from sticking. 5. When the cleaning process is finished, the system is ready again and waits for the start level to be reached again. 6. Usually after 4 weeks the fat and sludge containing main tank can be disposed by a disposal...

Elkuch Waste Solutions - WASTEWATER TREATMENT 4. Example: Design for a canteen with 1000 meals/day Project data At peak times, up to a maximum of 1000 meals are prepared daily in a canteen. The kitchen waste water must be pre-treated before being discharged into the public sewerage system. The treatment of the kitchen waste water with the Hydronetik-system was specially developed to minimise the water level inside the main tank. This considerably reduces the disposal costs for the customer. The closed system prevents the formation of odours. The treatment process depends primarily on the...

Elkuch Waste Solutions - WASTEWATER TREATMENT In this example the 2nd method is selected and Q is calculated based on the operating mode. Q = (V x F) : (t x 3600) Qs = maximum waste water income [l/s] V = average daily volume of waste water kitchen operations: V = M x Vm M = Number of hot food portions produced daily F = Shock load factor depending on the operating type t = Average daily operating time in hours Vm = Operation type specific water quantities per meal portion For the operatione type canteen the following parameters have resulted: The determination of the nominal size results...

Elkuch Waste Solutions - WASTEWATER TREATMENT • What is the recommended capacity/layout of a system? The design of our waste water treatment system is calculated based on the water input from the kitchen (l/s) (chapter 4). • What size of system room do I need? For usual grease separators + treatments you need about 10-30 m2. Due to our "All-In-One" system we only need about 5-15 m2, depending on the size of the plant. • What tank sizes are available?
