  • Production performance prediction during steam assisted gravity drainage process in anisotropic reservoirs

    Although steam assisted gravity drainage (SAGD) technology is an effective thermal recovery process for heavy oil reservoirs, it consumes a mountain of natural gas and produces tons of greenhouse gas. Therefore, it is of great importance to predict the production performance during production period. In this paper, we extend Reis's research (Reis, 1992) to calculate SAGD production performance in ...

  • Seven Ways Your Facility Isn’t Meeting Effluent Regulations and How to Solve Them

    Whether you own, operate, or help manage a municipal or industrial facility that deals with wastewater, it’s important to understand how wastewater treatment can play a significant role in the overall health of your business, especially when it comes to meeting effluent regulations. This is an important part of the wastewater treatment process to consider, as ignoring it could earn your ...

  • What is so hard about drainage modeling?

    Drainage modeling often suffers from the misconception that it is simple, but while it appears obvious that rain water will flow to the lowest point, the physical processes involved are not always well-understood or predictable. Drainage models attempt to predict that part of the water cycle that involves rainfall and its consequences, including potential flooding. Although flooding is, at its ...

  • Evolution of an integrated 1D/2D modeling package for urban drainage

    Introduction: Recent flooding events in North America have revealed deficiencies in existing stormwater infrastructure and management practices. The development of effective and efficient designs requires a comprehensive understanding of flooding in urban areas and complex open channel and overland flow systems. Traditional one dimensional (1D) models are used to simulate flow in river ...

  • Prediction of three–phase saturation profiles from two–phase capillary pressure curves as a function of wettability

    Gravity drainage of oil with gas is an efficient recovery method in strongly water–wet reservoirs and yields very low residual oil saturations. However, many of the oil–producing reservoirs are not strongly water–wet. Thus, predicting the profiles and ultimate recovery for mixed and oil–wet media is essential to design and optimisation of improved recovery methods based on three–phase gravity ...

  • Challenges of Modeling a Tidal Influence Conveyance System, a Seattle, Washington Case Study

    Hydraulic modeling of a drainage basin usually involves system representation of a network that flows either by gravity downhill or a force main via an outfall to a receiving water body or a treatment plant. And calibration of such a system is usually straight forward. Occasionally, engineers encounter a “City of New Orleans” type of conveyance system, where most of the storm drain network is ...

  • Our Conical Cone Tanks Are Now WRAS Approved For Drinking Water Storage

    When it comes to quality, Enduramaxx is there. And our cone tanks (conical tanks) are no exception. We are proud to announce that they have just been granted WRAS certification. The Water Regulation Authority Scheme approval means that these tanks are approved for the storage of emergency water for human consumption. This means our cone bottom tanks can be used for applications for storage of ...

  • Pore–scale analysis of the effects of contact angle hysteresis on blob mobilisation in a pore doublet

    The mobilisation of residual oil blobs in porous media is hampered by the so–called Jamin effect. We studied the Jamin effect experimentally in a pore doublet model and explain it through contact angle hysteresis. We measured the contact angles (in 2D and 3D) and the mean curvatures of a blob trapped in the pore doublet model. Due to gravity effects and hysteresis, the contact angles were ...

  • Hill Biscuits, Ltd. - Case Study

    Wastewater issues from solidified palm oil combined with flour resulting in high operating costs and surcharges. Plant had conventional grease trap to capture the fat. The two sections of the existing grease trap were isolated and the primary section utilised as the influent source via a dip tube. A 100 GPM Fogbuster Jr, with automated control system was installed with a low shear Moyno pump for ...

  • Impediments to the adoption of alternative sewerage in South African urban informal settlements

    In recent decades South Africa has witnessed a substantial growth in its urban population. This growth has been accompanied by the mushrooming of informal settlements (shantytowns) flanking more formal development. The lack of adequate urban drainage in many of these informal settlements has resulted in extremely polluted environments which add to the disease burden of the poor people who live ...

  • Natural clinoptilolite composite membranes on tubular stainless steel supports for water softening

    Disk membranes generated from high-purity natural clinoptilolite mineral rock have shown promising water desalination and de-oiling performance. In order to scale up production of these types of membranes for industrial wastewater treatment applications, a coating strategy was devised. A composite mixture of natural clinoptilolite from St. Cloud (Winston, NM, USA) and aluminum phosphate was ...

  • Flooding of lowland peatlands in Southeast Asia

    Vast lowland areas of Southeast Asia will be frequently and irreversibly flooded before the end of the century unless action is taken to stop the destruction of peatlands. A radical change in land-use is needed. In particular the palm oil and pulp wood sectors must stop developing new plantations on peat and plan to phase-out existing drainage-based plantations before they are flooded. If no ...

  • How to Plan Stormwater Management for Urban Areas

    Water is a vital commodity in our lives, but it is possible to have too much water all at once in our lives, especially following violent storms or snow melt. This excess water, lying on the ground, swelling rivers, canals and drains to over-capacity is known as stormwater. In order to make the best use of this water, local authorities need to safely contain stormwater while any ...

  • Extension of an existing model for soil water evaporation and redistribution under high water content conditions

    Most crop, hydrology, and water quality models require the simulation of evaporation from the soil surface. A model developed by J.T. Ritchie in 1972 provides useful algorithms for estimating soil evaporation, but it does not calculate the soil water redistribution resulting from evaporation. A physically-based model using diffusion theory, described previously by Suleiman and Ritchie in 2003, ...
