How can you maintain a grease trap cleaned?

Cut down on smell & no solid grease

Asked on 16 February 2024
Expert's Answer:

To maintain a grease trap and reduce odour and solid grease buildup, we suggest to integrate a drain maintenance program system, specifically the product “DRAIN GUARD 9023”. This product is designed to restore and maintain drainage systems by dissolving and breaking down organic materials such as starch, food remains, and existing grease. It reduces the need for costly emptying, prevents the buildup of grime, and maintains the flow of drainage. Additionally, it is harmless to use, doesn’t damage materials like steel, copper, and PVC, and is odour-free without containing toxic gases. With the use of DRAIN GUARD 9023, it is environmentally friendly and safe for use in systems where wastewater is discharged into the public drainage system. This ensures that the maintenance program is not only effective but also aligns with environmental safety standards. This approach provides an effective solution for maintaining a grease trap, cutting down on smell, and preventing the accumulation of solid grease.

Regarding Halal / Haraam definitions when it comes to alcohol.

Your website shows the following text “The fine line is this, it considers not haram when the haram medium (in this case, it is the cleaning detergent that contains alcohol) is washed or rinsed with water after it is applied. This thus removes the alcohol impurities from the surface and in turn, it retains the pureness of the surface. ”

Where is the fatwah or proof from scholars that simply washing with water can remove impurities of Najis caused by alcohol in detergents.
Many people say it requires a full ritual cleanse.

Can you provide some details for why this is an exception?
It would really help our restaurant.

Asked on 11 January 2024
Expert's Answer:

It’s important to note that interpretations of Islamic rulings can vary among scholars and schools of thought. The concept of purification after the contact of impure substances, such as alcohol, is indeed present in Islamic jurisprudence. The idea is that water is considered purifying and can remove impurities from a surface.

However, the specific details and requirements for purification may vary. Some scholars may argue that a simple washing with water is sufficient, while others may insist on a more rigorous purification process, often referred to as “istinja” or “tahara.” This process should done by washing three times with kurr or under-kurr or running water.

Based on the concept of istihlak, refers to a process of perishing. In this case, the element (which is the cleaning detergent that contains alcohol) that is being perished an impure one. There are several processes that could perish or remove impure elements. The common example given by scholars of jurisprudence (fuqaha’) is the mixing of a drop of alcohol with an abundant of water. This theoretical concept of istihlak thus involves an insignificant amount of impure element, mixed with other elements that are beneficial, clean, halal and in abundance, to the extent that the impure element loses its characteristics, like its colour, smell and taste. This type of mixing would thus remove the characteristics of the impure element(s) from the end product from the Shari’ah perspective which is the cleaning detergent itself and also the action of rinsing after appling the cleaning detergent that contain with alcohol. Reference: az-Zuhaily, Qadaya al-Mu’asirah, Damascus, Dar al-Fikr, 1428H/2007, pg. 72.

Having mentioned these points, it’s important to note that we at Orapi are not experts in Islamic knowledge. For accurate guidance, we recommend consulting reliable Islamic sources, such as fatwa websites, books of fiqh (Islamic jurisprudence), or seeking advice from a qualified Islamic scholar or mufti. They can provide insights based on their knowledge and understanding of Islamic teachings.

When looking for grease, consider the following criteria:

  4. Base Oil: Different base oils have varying properties. Common types include mineral oil, synthetic oil and vegetable oil. Select one that suits your application’s temperature and load requirements. 
  5. Additives: Grease often contains additives for enhanced performance such as anti-wear, corrosion protection and extreme pressure additives.
  6. Temperature Range: It is also known as operating temperature. Ensure the grease can operate within the temperature range of your equipment. Some greases are formulated for high-temperature applications, while others are better for low temperatures.

Our company standard to wash veg is 50-100ppm for 1-2min. Please let me know whether the strength and time combo that we follow will be effective enough to serve its purpose.

If not how can we change the time- concentration according to other than the 50-200ppm; 5min. We are looking for a narrow range which can cover all the veggies with its effectiveness.

Asked on 23 June 2023
Expert's Answer:

To simply answer your question – YES! Up to 200ppm of AV Chlorine with our product OPAL 4978 in 1-2minutes is sufficient to generally clean & sanitize vegetables fruits and salads.

As a matter of fact – different ppm is required for different types of vegetables, fruits or salad- this is solely base on each different rigid shape/ texture, how they are produced- using pesticides or naturally grown and where they are produced. How it is transport and packaged is also a different factor all together. However, general rule of thumb, 50-100ppm of AV Chlorine in 1-2minutes contact time is sufficient and do not require rinsing after soaking.

NOTE: Any proportion below 200ppm AV Chlorine does not require rinsing. Above 200pm require rinsing with portable water.
