Tapping new aquifers with drilling, well-building technology

Experts agree that, in the future, there will be a massive rise in worldwide requirements for clean drinking water, boosting efforts toward groundwater development among other water improvement industry sectors.

“With our innovative drilling and well-building technology, we will play an active part in the growth which is forecast for the water market,” says Christian Runge, managing director of EDI Exploration Drilling International GmbH in Haltern, Germany. “The significant advantages provided by our technology in terms of cost and quality offer the best preconditions for this, which is demonstrated by the fact that the Government of Namibia and Coca-Cola in Pakistan are already using our systems.”

EDI’s objective is to find water resources below ground under financially viable and environmentally sustainable conditions, and to ensure their long-term exploitation. For this purpose, it has developed a drilling system with which underground drinking water deposits can be accessed up to 40% more cheaply than so far possible using conventional processes. The special feature of this patented drilling process is that with a single bore hole as many samples as required can be taken at different levels, which also provides the savings in time and expense.

A significant advantage of the EDI system is that it allows mixture of aquifers at different levels to be avoided, which enables an unambiguous and reliable analysis of each individual aquifer and avoids cross contamination by ones that may be under the influence of nitrate or pesticides from the surface. It also has its own dedicated technology for preventing the mixing of aquifers in the subsequent well-building process.

The scientific concepts behind ACT are application of an appropriate bacterial cocktail for a given type of polluted water, and an innovative chemostate. The process is maintained in a balanced state of bacterial growth and organic compound degradation. Thanks to low concentration of bacterial cells, no aggregates are formed, and each bacterium acts as a single cell which increases the surface available for the process and enables biodegradation at a much higher efficiency.

The ACT operates as a continuous flow reactor without using activated sludge. The bioreactor can thus be applied on site while using available infrastructure with high flexibility for modulation of the process saving dramatically in operational and maintenance costs.

The operator can at any point in time, via various interaction channels, from a control center, a laptop or a cellular phone, see the real-time status picture, receive real-time sound and SMS alerts, and take action. Supervisors can receive automatic reports, update environmental offices on-line, and most importantly, effectively avoid catastrophes. Crises management is vastly simplified with BPC’s monitoring technology.

The fully automated system is comprised of a variety of on line sensors which feed the control unit information on various parameters such as: TPH, nitrogen, dissolved oxygen, TOC and temperature. The controller ensures to maintain optimum process balance between the flow rate, bacterial growth, additives and organic compound degradation.

With its process already fully operational, BPC offers potential customers chance to world experience its remarkable technology through a skid mount pilot system at minimal cost.

A multi-utility drilling project through a lime bed, marl layers and variegated sandstone to a maximum depth of 7.8m was prompted by installation of a gas pipe intended over a length of 12km from Lügde via Elbrinxen to Rischenau, Germany.

At short notice, utilities cut the distance by 75%, including for gas, power and water lines – the last exchanged due to insufficient diameters and sanitation needs. The boring company Meier Tiefbbau GmbH, of Hessisch-Oldendorf, applied its Tracto-Technik Grundodrill 15 N on a difficult 90m stretch under an Elbrinxen road, stream and water mill trench.

The rig’s compact construction – with auto-bore and digital instrument display, as well as a Grundorock mud motor – ensured completion in narrow streets and alleys without causing roadblocks. Using horizontal directional drilling (HDD) methods, installation of the 4 HDPE pipes in a pipe bundle was achieved without difficulty in 1-1.5 hours.

Ultrafiltration specialist to present new modular rack system

Click here to enlarge image

The new T-Rack® modular rack design to be exhibited by inge AG at the IFAT trade fair [Stand 213, Hall A1] in Munich from May 5-9 has been optimised to provide sharp improvements over conventional systems in regard to both the technical and economic aspects of module installation. Depending on the quantity of water being treated, the size of the rack can be flexibly adjusted. The dizzer® ultrafiltration modules featuring inge’s Multibore® membranes are tightly packed together in the T-Rack and are already equipped with pipes, meaning that additional piping is no longer required.

The system saves a large amount of space, offering significant advantages over conventional systems that require about 70% more space than the new T-Rack. By using this new approach, it is possible to cut the total capital costs of an UF system by 5% or more depending on the scale of the system being installed. This is ideal for companies that need process water or require a means of cleaning their wastewater, as well as for municipal drinking water and wastewater treatment facilities and sea water desalination plants.

Another advantage of ultrafiltration in all its fields of application is the fact that, however poor the quality of the initial water, the filtrate is of consistently high quality with no variation. Viruses, bacteria and suspended solids are filtered out using a purely mechanical process. Even though the capital costs are typically higher to begin with, a sustainably cost-effective operating concept means that these costs are recouped more rapidly than with other systems.

Click here to enlarge image

Fozmula has created its G/LL148 series of gauges in response to demands for a more effective and practical solution for liquid level monitoring in bulk storage tanks. The retrofittable gauge delivers a continuous display of the tank’s contents and harnesses all of the advantages given above. Additionally, Fozmula specifically designed it to be a closed hydrostatic system which does away with the need to continually push or pull a button or lever to re-prime the gauge each time a reading is required.

This British designed and built system comprises three key parts combining to deliver the full operational function. These are:

    a) A pressure gauge of either 52mm or 100mm diameter mounted remotely from the tank.

    b) A pressure transmitter of robust and durable construction which lies on the base inside the tank and supplies pressurised air to the gauge. The pressure sent to the gauge is based upon the height and specific gravity of the liquid being measured.

    c) A length of copper capillary tube which connects the gauge and transmitter.

      The gauges, which may also be self-branded and fitted with anti-fogging glass, can be fixed in one of two ways. The smaller 52mm diameter gauge is designed to be mounted in a panel, whilst the larger 100mm gauge is usually mounted on or near the tank where its scale can be read from a distance. Both gauges can be sited at a convenient position up to 10 metres from the tank.

      Fozmula designed the transmitter unit with a large air capacity to minimise maintenance and provide long, reliable and efficient service. It’s manufactured from brass, polypropylene and Viton rubber making it corrosion-free and compatible with more than just fuels and water-based liquids.
