Reverse Osmosis Emergency Treatment Plants
Glan Agua will provide a skid-mounted reverse osmosis treatment system for the removal of nitrates and ammonia in water treatment processes. Reverse Osmosis is used to separate solutes from water, relying on the physical and chemical properties of the solutes for separation. A high-pressure feed stream is directed across the surface of a semi-permeable material, and due to a pressure differential between the feed and permeate sides of the membrane, a portion of the feed stream passes through the membrane. As the water passes through the membrane, solutes are rejected and the feed stream becomes more concentrated. RO is a continuous separation process, and therefore there is no periodic backwash cycle. Two units in parallel are employed; The double pass units can remove up to 98% of dissolved organics and all colloidal and suspended matter larger than 0.5 micron. Glan Agua Ltd. have installed 2 no. reverse osmosis systems in Kiltiernan GWS WTP and Ballyaneen Rakerin GWS WTP.

Dissolved air flotation
Dissolved air flotation (DAF) removes suspended matter such as oils or solids in a water treatment process. The raw water is dosed with a flocculent and the subsequent floccs are then removed by the DAF process. Removal occurs in the DAF tank, where dissolved air is filtered from the bottom of the tank to the surface. This air forms tiny bubbles which attach to floccs causing them to float to the surface of the tank, forming a thick layer on the top of the tank. A scraper then removes this layer and the clarified water is drawn from the bottom of the tank for final clarification.
Glan Agua Ltd. have designed, installed, operated and maintained DAF plants as part of the Galway GWS DBO bundle no. 2, the Four Roscommon RWSS project and the Burncourt & Fethard RWSS.
Glass lined steel tanks
Glan Agua Ltd. have provided numerous glass lined steel tanks for use on water and wastewater infrastructures. Glass lined steel tanks are durable, inert, easily maintained, suitable for various uses as listed below;
- Biogas Digesters
- Aeration Tanks
- Slurry Tanks
- Bulk Material Silos
- Potable Water Storage
- Fire Storage
- Sludge Storage
Clarifiers / Lamellae plates
Final clarifier are utilised by Glan Agua Ltd. in both water and wastewater applications to allow any remaining biosolids to settle out of the wastewater at the end of the process. These solids are then removed from the hopper bottom of the clarifier and returned to the secondary treatment stage or onto the sludge treatment process in the case of Wastewater treatment processes and are drawn to the sludge thickening process for water applications.
A lamella clarifier or inclined-plate clarifier can be used in both water treatment systems and in wastewater treatment systems. The lamella clarifier consists of a series of inclined plates which allow a large area for settle ability; The inclined plates provide a large effective settling area for a small footprint. They are often employed in primary water treatment in place of conventional settling tanks, Glan Agua Ltd. have only recently installed numerous lamella clarifiers on the Roscommon GWS Bundle. Solid particles begin to settle on the plates and begin to accumulate in collection hoppers at the bottom of the clarifier unit.
Picket Fence Thickener
Glan Agua Ltd. has designed and installed numerous picket fence thickener systems for wastewater treatment applications. The glass lined steel tank or concrete tank are fitted with a picket fence-like mechanism which slowly rotates, ‘mixing’ the sludge and releasing entrapped gases and breaking down large areas of solids. The more sludge which enters the system the heavier the sludge blanket gets thus squeezing lighter sludge to the top of the tank which is then drawn off as supernatant to the secondary treatment process. The heavy sludge to drawn from the bottom of the tank to further sludge treatment.
Glan Agua Ltd. has installed and are currently operating and maintaining a picket fence thickener in Cavan WWTP and Cheekpoint WWTP.
Glan Agua Ltd. have designed, installed, commissioned and operated and maintained numerous aeration systems for wastewater applications.
Fine bubble Aeration systems; Fine bubble aeration systems involved a grid of disc like membranes which allow fine bubble of air to filter from the bottom of the tank to the top. Allowing maximum aeration for the biological process.
Agitator Aeration Systems; Involves the addition of air to the secondary biological process via mixers agitating the wastewater.
