Knowledge of water supply and drainage in building: how to select filter equipment

Nowadays, many friends like to fish their own bodies. Filters are the equipment for aquarium to keep the water clean. How do we choose the filtration equipment?

The power device of the pump filter system, divided into two kinds of submerged and water free type, is driven by the frictionless electromagnetic rotor. It can operate permanently, the submerged water is a fully sealed structure, and the water is cooled by the water. The rotor coil will burn down the filter tank (box) on the upper part of the fish tank because of the high temperature, and the water pump is made by the submerged water pump. Or the water pump driven water supply, by reducing the flow mouth, making the flow back to the fish tank, maintaining the shorter maintenance time is more convenient, but it does not recommend the water filter, which is used for the water pump at the bottom of the water pump, to install the filter box directly under the water pump at the inlet of the water pump, to maintain a short time in the maintenance interval of the water pump at the bottom of the water pump. Therefore, the price convenient external filter is generally barrel structure. The pump is usually made directly in the barrel cover. The water pump is pumped from the fish tank through the pipe. After the physical and biochemical filtration in the bucket, the water pump flows back to the fish tank through the outlet pipe. The filter body is large, the maintenance time is long, the cleaning is inconvenient and the price is expensive.

The bottom filter is used as a large volume of filter material (percolation filter layer) with a bottom sand sand layer. Through the submerged water pipe laid under the sand layer, it is pumped through the submerged water pump to achieve the physical filtration and biochemical filtration. (the principle is similar to the submerged filter) because of the larger filter body (sand), so the maintenance time is longer (half a year). Above), but maintenance is extremely inconvenient.
