MO-1000 Water Treatment System for Effective Deep Desalination

The MO-1000 water treatment system is designed for deep desalination of source water, which complies with SanPiN 2.1.4.1074-01. The equipment is mounted on a frame made of anodised aluminium machine profile equipped with vibration-isolating wheels. Pipelines of the water treatment plant are made of polypropylene pipes, electrical communications are laid in polyamide corrugated pipe.

Water treatment technology. Source water is supplied from the water supply system to the injection reactor of the plant. In the reactor oxidation by injected air of hydrogen sulphide, iron and manganese compounds contained in water on fluidised catalytic filling takes place.

The suspended solids formed during oxidation are collected in the fixed bed of the catalytic backfill. The water from the reactor flows to the multi-patron filter, where the remaining fine suspended solids, wear products of the catalytic backfill and dissolved organic substances are captured on filter-sorption cartridges. The water is supplied with a dose of antiscalant and is pumped by a high-pressure pump into the RO membrane housing, where it is separated by the membrane into a desalinated permeate and a salt-enriched concentrate.

The concentrate is discharged into the sewer. The treated water is fed into a storage tank. From the storage tank the water is supplied to the consumer by a stainless steel distribution pump.

Each time the storage tank is filled, the system stops operation and automatically backflushes the catalytic backfill in the reactor with water from the storage tank. The system automatically stops operation when the pressure in the inlet water pipe drops below 0.2 MPa and informs the user about this emergency situation by switching on the red coloured indicator on the control panel. The system informs the user about the need to replace filter-sorption cartridges by switching on the yellow coloured indicator on the control panel.

The system is equipped with a device for automatic water drainage from the multipatron filter housing to prevent untreated water from entering the RO membrane when replacing the filter-sorption cartridges. The system is equipped with a unit for automatic withdrawal of the RO membrane after start-up to the operating mode according to the salt content in the permeate. The unit provides water quality at the outlet in accordance with GOST 9.314-90 "Desalinated water" for the first category of water at source water corresponding to SanPiN 2.1.4.1074-01 "Drinking water.

Hygienic requirements for water quality of centralised drinking water supply systems. Quality control". When functioning, the system consumes filter-sorption cartridges, antiscalant and electricity.

Directly for water treatment the system consumes up to 2.5 kWh per 1 m3 of treated water. The drainage water of the system is non-toxic and its discharge into the sewerage network is allowed without additional treatment. The system is fully automated and does not require user control.
