Self-cleaning pre-filter

The pre-filter comes with a mesh size of 100 micron. As such, it removes all bigger particles to protect the UF membrane and prolong service intervals. The pre-filter is automatically backwashed together with the UF membrane. The unit also includes a pressure sensor to initiate separate pre-filter backwash or signal that manual cleaning is needed.

Standard UF membrane

The ultrafiltration membrane module consists of a hollow fibre, dead-end, outside-in membrane PVDF module with a pore size of 0.03 micron. The filtration is driven by a 1.1 kW Grundfos CRIE, stainless steel pump with a variable speed motor.

The control unit is a PLC with a 7” touchscreen. The control strategy is parametric and automatically adapts to changing water qualities in order to prolong service intervals.

Air scouring

The air scouring module enhances the efficiency of the UF membrane backwash by inducing air bubbles before the backwash. This physical cleaning of the membrane reduces chemical consumption and prolongs service intervals.

The air scouring module is driven by a 0.75 kW compressor.

The air scouring module also enables testing of membrane integrity by a semi-automatic pressure decay test.

Chlorination

This module enables disinfection by adding chlorine to the treated water. This prevents bacteria or viruses from re-populating the water after treatment.

The chlorination module also allows chemical-enhanced backwash to reduce biofilm growth on the membrane surface. The chlorine is dosed by a Grundfos SMART Digital dosing pump that includes an integrated flow meter to allow accurate flow proportional dosing.

Internal CIP

This module enables chemical cleaning of the UF membrane when it cannot be cleaned hydraulically or physically. Chlorine is dosed into the closed circuit and circulated to dissolve fouling on the membrane.

This automated procedure maintains water production capacity and prolongs service intervals.

The CIP module utilises the chlorination module and a self-priming circulation pump.

Level sensing

The level sensing module consists of an external level sensor which can be added to a locally sourced external water tank. The level sensor works within a range from 0 to 0.6 bar which ensures that it can measure up to 6 metres of head. The level sensor sends out an analogue 4-20 mA signal which is used to control the water production of the complete system.

Activated carbon filter

The activated carbon filter performs final polishing of the treated water. The AC filter is used to remove certain chemicals, particularly organic chemicals, from the water. The AC filter is also used to remove substances that give water an objectionable odour or taste, such as hydrogen sulphide or residual chlorine.

The module is backwashed and rinsed in an automated sequence.

UV disinfection

The UV disinfection module can be added as a final disinfection step to protect water consumers against the risk of bacteria and re-growth of viruses.

The 70 W UV lamp is designed for easy replacement with a minimum lifetime of 9,000 operating hours.

The module includes a light intensity sensor which monitors that the lamp emits the specified UV dosage and sends a warning signal if it does not.

Distribution

The distribution module allows the treated water to be pumped to an external storage tank. It is an automated process that uses the backwash pump.

The module includes a mechanical measuring device of max. 2.5 m3/h which sends out a pulsed signal so that the total amount of produced water can be documented.

Solar package

The solar package module enables solar power to reduce the operational cost of running the unit. The solar module includes a bi-directional inverter of 2,000 VA, 1,600 W with an integrated charge controller so that the unit can be powered by a combination of grid and solar power.

The module also include two 200 Ah gel batteries so that the unit can produce at least 6 m3 water on battery power.

Remote management

The remote management module connects the unit to an internet-based data management programme.

The data management system provides real-time operational status of the connected systems.

Warnings and alarm notifications can be broadcast as emails and text messages.
