What is DEFERUM?

This hydro-automatic system DEFERUM with floating filtering media is designed for the non-reagent removal of high levels of dissolved:

•Iron (up to 75mg/l), •Dissolved gasses

oHydrogen sulphide oCarbon dioxide oMethane oRadon oOdour oEtc

Deferum also provides partial removal of manganese. However, the targeted manganese removal can be provided by the special system – a modification of DEMAGNUM The process can be classified as intensive aeration/degasification followed by filtration system which uses unique AKV aerator/degasifier and Polymer Floating Filtering Media.

PROCESS

First Treatment Stage - Aeration

Feed water is pumped from the borehole and supplied at

4.0 bar to the aerator-degasifier (1) where dissolved

gasses are removed from water and atmospheric air

oxidizes bivalent iron and partially ions of manganese. On

each hydrorobot (2) is available two aerodegasifiers (1).

Aerodegasifiers work as ejectors. The first aerodegasifier

(1) has trumpet connection with a hydrorobot siphon (2),

therefore atmospheric air is sucked in (induced air) to the

first aerodegasifier (1) through a siphon of the

hydrorobot (2). The second aerodegasifier (1) sucks

atmospheric air through a siphon of the hydrorobot (7),

through a trumpet connection with a hydrorobot siphon

(7) too.

Second Treatment Stage – DEFERUM Filtration

Further, feed water flows down the hydro-robot (2) and

through the distribution system (3) arrives into the

hydro-automatic filter with floating filtering media (4),

where impurity particles are arrested throughout the

depth of the filtering bed (4).

The mesh of the holder (5) keeps the floating media

within the filter tanks (4).

Third Treatment Stage – DEMAGNUM Filtration

After filtration, treated water gravity-flows into a filtrate

collector via the discharge pipe/reactor (6) to the

hydrorobot (7), hence through the distributor (3) go

for next filtration in the floating media (4), which keep

by the holder (5).

The filtrate flows to the tank of pure water, through a

pipe-11 and then a delivery pump forwards purified

water to consumption.

Backwash and Settlers

Gradual fouling of the bed increases its resistance, raising the water

level in an adjacent 'hydro-robot' until it reaches the top of a siphon.

This draws water out of the filtration chamber at such a speed that flow

through the filter bed reverses, and the filter bed is backwashed. There

are no sensors, electronic controls, floats or other moving parts to worry

about

i.e The hydrorobot and the filter media (4) are the connected vessels

(communicating vessels), therefore with by increase in resistance of

media-4 (from pollution) water level increase an in the hydrorobot and

in its siphon, till water overflow through a siphon and level increases of

water in the hydrolock (8), therefore siphon of hydrorobot is closed

from sucking of air to a siphon (i.e to aerodegasifier). In a siphon will

the vacuum (because of aerodegasifier work). Water in a siphon do

falling downwards and backwashing of the filter media (4) begins, i.e

as fouling of the filter increases, the water level in the hydro-robot rises,

causing the filter to switch into backwash mode.

Purified water from the above-filter section drops down and expands

the filtering bed (4), washing out the accumulated impurities. When

the water level in the above-filter section drops down to a pre-set point

(pre-set during commissioning), the hydro-robot stops the backwash

and switches the filter into a new filtration cycle, after removal of water

from the hydrolock (8), through a small siphon (9).

Fourth Treatment Stage - Dosing

For increase in an pH of artesian water, till 6.8 to 7.8 the technological

decision can be applied:

From the tank (19) with solution of the lime, by the instrumentality of

the batcher (17) do dosing to pipeline of raw water.

For disinfecting a filtrate, also for oxidation of ions of manganese 8 the

technological decision can be applied:

From the tank (20) with solution of oxidant, by the instrumentality of the

batcher (18) do dosing to a Pipe/Reactor (6).

Backwash water go from the settler to the pump (14), next through the

filter-press (15) to the hydrorobot (2). The press cake goes to the

pallet (16) and then takes to a city dump.

Fifth Treatment Stage – Clear Water

A delivery pump forwards purified water to consumption after filtration

from DEMAGNUM.
