SU1756289A1 - Method of cleaning natural water from iron - Google Patents

Abstract

The essence of the invention natural water is aerated in a layer no more than 1.2 m high for at least 20 minutes at an air flow rate of 6-9 m3 per 1 m3 of water, boiled for at least 15 minutes, centrifuged, cooled to 24 ° C, filtered through the material of a spatial-globular structure based on phenolic polymers 3 tab.

Description

The invention relates to chemical technology for treating aqueous solutions using mechanical cleaning, coagulation, flocculation, disinfection and sedimentation of suspended solids and can be used to correct iron ions in water and deironing drinking water.

The purpose of the invention is to increase the degree of purification from iron while the water softens.

The method is carried out as follows

Water enters the 1.2 m deep aerator, at the bottom of which porous ceramic diffusers are mounted for spraying compressed air with a flow rate of 6–9 m3 of air per 1 m3 of water, aeration time is 20 min, then water enters the thermal reversible thermal humidifier, for 15 min. After heat treatment and centrifugal water is cooled to 24 ° C in cooling systems and in front of clean water tanks are passed through cartridge filters with filter material from the basis of phenolic polymers of highly permeable spatial globular structures.

(CBC) with a retention spectrum up to 1 µm CGP are capable of sorbing a mouse to iron and ions. The CG regeneration is carried out by back-blowing with compressed air and rinsing with a liquid in a circular cycle using a distributor faceplate

Example The study was conducted at a water treatment plant. The quality of water is determined by the methods of GOST Vodortiev and according to generally accepted methods of water analysis Physical and chemical characteristics of the water under study; turbidity 9.6 mg / l, color 48 °, pH 7.65, alkalinity 7.25, hardness 725 mg-eq / l, chlorides 12.5 mg / l, nitrite 0.036 mg / l. nitrates 0.15 mg / l, iron 1 95 mg / l, ammonia 0.58 mg / l sulfates 31.5 mg / l, cjn-op 0.32 mg / l, 1.25 mg-eq / l, MD2 36.25 mg - equiv / l, oxidability 11.5 mg / l 02.

Large concentrations of substances are obtained by modeling on the source water. Research wire H in a laboratory setup that includes aeration - degassing - boiling - centrifuging - cooling the filter cartridge

After seven days of storage, the water blooms, acquires tobacco color, transparency - 10 source water
