WATER AND WASTE

 

At Iskhus we understand that power is fundamental to business. We know that business requires the highest power quality, at the best price, and at the highest level of efficiency, whilst using less energy with improving output. The reduction in emissions is assisting in the conservation of our planet.   The biggest corporations in Southern Africa have relied on our advice, technology and proficiency to implement to meet their diverse and complex energy saving needs. 

Our core business is saving energy for our clients. What is Energy Efficiency? Simply, Energy Efficiency is using less energy to provide the same level of energy service. Making homes, vehicles, and businesses more energy efficient is seen as a largely untapped solution to addressing the problems of pollution, global warming, energy security, and fossil fuel depletion. 

The idea of meeting energy needs by increasing efficiency instead of increasing energy production. At Iskhus Power we break down the energy sector into onsite energy efficiency, onsite renewable energy, offsite renewable efficiency and Water.

   



We can save you money, improve perfomance and help the environment.

How?


1. Audit

Water audits are essential for any industry that utilizes water in their process, product or just for general use.  The audit encompasses a survey of the total area in question, and determines the quantity and quality of all water uses, and where it is being discharged.  The details from this study are used to form a mass balance picture of the water uses and waste discharge.

The outcome of the audit is to highlight possible areas of water savings, optmisation, and re-use, thus producing a cost saving to the company.  The final discharge water can then be treated for other uses or lower of discharge costs.  The audit assists to determine the feasibility of various possible water treatment regimes.

 A dedicated and knowledgeable team will be used for the audits, and a comprehensive report presented to the clients.

2. Water Processing

The processing of water is a complex and varied subject.  There are as many ways to treat the water, as there are the various contaminants and contamination sources. 

Production of water depends a lot on the source from which it is obtained.  In most cases, raw water sources such as rivers, boreholes, dams, etc are chemically fine, but needs to be treated for physical and biological contamination.  Physical processes such as membranes or settling, with or without chemical addition can be used to produce a reasonable quality of water for potable (drinking) and process water uses. Sources such as already potable reticulation systems can be contaminated through various means.  Partial or at use treatment can de considered in this case.

For rural communities, the lack of on-site power limits the use of various water treatment systems.  ISKHUS Water Optimisation has linked various treatment regimes with renewable and low energy systems, to ensure that during the day, good quality water is produced, with no need for on-site power.

ISKHUS Water Optimisation has a number of in-house treatment equipment and chemicals that can be used for a variety of water and waste water treatment needs.

3. Water Harvesting and Capture

Harvesting and capture of water is a previously overlooked source of reasonable to good quality water, especially in those areas that have a reasonable to high rainfall.  The feasibility of harvesting and capture will depend on a number of factors such as:

  • Annual and seasonal rainfall figure.
  • Area of roof for capture.
  • Possible utilization capabilities for the captured water.

ISKHUS Water Optimisation has a number of innovative technologies to assist in the harvesting and capture, and subsequent treatment of the water prior to utilization.

4. Water Recycling and Optimisation

From the water audit mentioned above, the areas of possible water savings will be highlighted.  The following processes can then be taken to ensure that the optimal use of water is carried out:

 

  • Optimisation:  This would be through the optmisation of a process plant or system to ensure the minimal use of water.  For example, the use of rinses within a metal plating industry can use at least 60% less water if the correct type and flow of rinse is used.   This could also include the utilization of water from one process into another, if the quality permits.
  • Recycle:  Recycling of water can be achieved through an at-source treatment with the correct technique, thus removing the contaminants from the water, and discharging only the unwanted part, thus recycling clean and applicable water back to the process.  This reduces the uptake of water from the feed water source.
  •  Re-use:  Once final discharge has been reduced to its minimum, the waste water could be treated further through a combination of systems to re-use either all or part of the stream back into the process plant.  This utlisation could be to none essential areas or to other uses that could use that quality of water.

 

ISKHUS water optmisation have a myriad of technologies and processes that can be used either individually or in combination, to be used in any of the above areas.  The best technology or process will be identified and applied in the correct and optimal way to ensure 

5. Monitoring and Control

The monitoring and control of water treatment systems are of utmost importance as this ensures that the integrity of the plant and the application is kept at its optimum.  The control of the process includes the process parameters such as flow, volume, etc, chemical constituents such as Dissolved solids, ph, etc, as well as the energy monitoring.  This total package ensures that the processes that are implemented are kept optimal, and thus the savings maintained.

 

Within the whole ISKHUS Group, a tailor made system can be designed, installed and maintained, with data being shown at point of use, or through remote display and control to various areas.
