Design of water circulation and water treatment for edgeless (boundary) swimming pools
1. Water cycle design
The main effect of the borderless (boundary) swimming pool is the effect of pool water and stacked water, and the water circulation of the water body is an important part of the design. The design of the borderless (boundary) swimming pools abroad is a mixed flow circulation method, and the countercurrent circulation method is generally designed in China. This is the most critical and the most important link in the design phase of creating a borderless swimming pool.
The water stacking method can be designed to overflow and stack water on one side, two sides and three sides, and rarely design to overflow and stack water on four sides.
Overflow cascading water can be designed to use a circulating filtration system for water treatment as the source of overflow cascading water, but rarely use a separate overflow cascading system and circulating filtration system separately set form.
There are three ways to design a balanced (balanced) pond: an independent balanced (balanced) pond, an overflow return drain as a balanced (balanced) pond, and an overflow return drain and balanced (balanced) pond as a balanced (balanced) pond. The main design method is to design the overflow and return water ditch as a balanced (balanced) pool.
2. Design of balanced (balanced) pool
The effective volume of the design of a balanced (balanced) pool shall be calculated according to the following formula:
In the formula: Vj—effective volume of the balanced pool (m3);
Va—the amount of water discharged by each swimmer after entering the pool during the maximum swimming and splashing load (m3). Take 0.06m3/person;
Vd—the amount of water required for backwashing of a single filter (m3);
Vc—the amount of water (m3) required to fill the pipes and equipment of the pool water circulation purification treatment system;
Vs-the amount of water (m3) required for the operation of the pool water circulation purification treatment system;
As—Surface area of pool water (m2);
hs—The thickness of the overflow water layer (m) when the water overflows from the pool, which can be 0.005m~0.01m.
In the case of overflow return ditches as a balanced (balanced) water tank, probes and detection facilities for water level status and switching status shall be provided, with process water level display and make-up water level, maximum water level display, and automatically open or close the inlet pipe valve and ultra-low Water level and ultra-high water level device.
3. Design of the water treatment system of the non-edge (boundary) swimming pool
The supporting facilities of the non-edge (boundary) swimming pool mainly include: circulating water pumps, filtration facilities, water quality balancing devices, disinfection equipment, constant temperature equipment, air dehumidification and air conditioning disinfection systems, lighting systems, pool cover devices, automatic cleaning facilities and intelligent control housekeeping systems .
