Abstract
An apparatus for optimizing water purification profile, has a front processing unit, a booster pump having a water inlet, a rear processing unit, a waterflow control unit, an emission control unit, a control circuit, and a temperature sensing probe. The front processing unit is connected to the water inlet via a pipe. The control circuit corresponds to the emission control unit. The temperature sensing probe senses water temperature. The control circuit is connected to the temperature sensing probe whereby automatically adjusting time of producing purified water in a periodic cycle. The apparatus implements a constant water utilization rate as water temperature changes.

A method for purifying waste water using a water purification apparatus, the water purification apparatus comprising:
- a reverse osmosis membrane module for separating the waste water into purified water and concentrated waste water, an emission control unit for controlling flow of the concentrated waste water, and a temperature sensing probe, the method comprising:
- separating waste water into purified water and concentrated waste water using the reverse osmosis membrane module and discharging the purified water;
- controlling said emission control unit to be switched off for a time interval T, whereby directing the concentrated waste water to flow back to the reverse osmosis membrane module;
- controlling said emission control unit to be switched on for an emission time, whereby directing the concentrated waste water to flow through said emission control unit;
- measuring a water temperature C of the waste water with the temperature sensing probe;
- and
- calculating a time interval T1 according to the formula T1=T/[1−(25−C)×3%] and controlling said emission control unit to be switched off for the time interval T1 whereby directing the concentrated waste water to flow back to the reverse osmosis membrane module.
A method for purifying waste water using a water purification apparatus, the water purification apparatus comprising:
- a booster pump (4) for increasing water pressure of waste water, the booster pump (4) having a first water inlet (41) and a first water outlet (42);
- a reverse osmosis membrane (5) for separating the waste water into purified water and concentrated waste water, the reverse osmosis membrane (5) having a second water outlet (51) and a third water outlet (52);
- a waterflow control unit (6) for controlling flow of the concentrated waste water from the second water outlet (51) to the first water inlet (41);
- an emission control unit (9) for controlling flow of the concentrated waste water;
- a fourth water outlet (10) for discharging the concentrated waste water;
- a control circuit (11) for controlling the emission control unit (9);
- and a fifth water outlet (8) for discharging the purified water;
- wherein:
- the reverse osmosis membrane (5) is connected to the first water outlet (42);
- the waterflow control unit (6) is connected between the second water outlet (51) and the first water inlet (41);
- the emission control unit (9) is connected between the second water outlet (51) and the fourth water outlet (10);
- and the fifth water outlet (8) is connected to the third water outlet (52);
- the method comprising:
- a) setting a time interval T1 and an emission time within the control circuit (11);
- b) during the time interval T1:
- i) increasing pressure of waste water using the booster pump (4), flowing the waste water at an increased pressure through the reverse osmosis membrane (5), whereby separating the waste water into purified water and concentrated waste water;
- ii) discharging the purified water through the fifth water outlet (8);
- iii) switching off the emission control unit (9), whereby directing the concentrated waste water to flow through the waterflow control unit (6) to the booster pump (4) to mix with the waste water, and
- iv) repeating steps i) through iii);
- c) during the emission time:
- switching on the emission control unit (9), whereby directing the concentrated waste water to flow through the fourth water outlet (10) via the emission control unit (9) to wash the reverse osmosis membrane (5).
